Just take it easy peeling the backing off so the sticker stops on the application tape - then press onto the screen and peel the application tape off slowly leaving the vinyl stuck to the screen Shouldn't be too difficult, mine went on 1st time with no probs.

What I meant by not being forgiving is that as soon as the first spot touches you're committed. I think I bumped the headrest with my elbow as the tape approached the glass and it was downhill from there.
